Answer:

left circle: 6x + 2y

middle circle: 5x

right rectangle: 3x + y

Step-by-step explanation:

left circle: since it's the sum of the two rectangles connected to it, they must be added together:

4x + 3y + 2x - y

= 6x + 2y

right rectangle (this needs to be done before the middle circle): since u have the circle and the rectangle, u need to subtract the rectangle's value from the circle to find the value of this rectangle:

4x + 5y - (x + 4y)

= 4x + 5y - x - 4y

= 3x + y

middle circle: like the left circle, add up the two rectangles connected to it:

2x - y + 3x + y             (these last two terms are from the rectangle above)

= 5x

hope this helps!
